Karaoke Scoring Explained: How SongHub Grades Your Singing

After every performance, SongHub shows you a number. For some singers it is a fun game; for others it is a coach. But what is that score actually measuring, and how do you move it? This guide pulls back the curtain on karaoke scoring: the pitch tracking, the timing analysis, and what the numbers mean for your singing. Grab SongHub from the official SongHub download and sing one song first, then read on with your score in hand.

Understanding the score changes how you practice. Instead of a vague feeling that "the chorus was rough", you get a precise readout of which sections drifted and by how much. That turns every performance into data you can act on.

How the Score Is Calculated

While you sing, the app analyzes your microphone input in real time and compares it against the song note data. Three things feed the final number:

• Pitch accuracy. The biggest factor. The tracker detects the pitch of your voice many times per second and measures how close each moment sits to the intended note. Nailing the center of each note scores highest; drifting sharp or flat costs points in proportion to the distance.
• Timing. Starting each phrase on the beat and holding notes for their full length. Rushing the entrances is the most common timing deduction, especially on fast songs.
• Stability. How steadily you hold pitch through a note. A note that starts on target but wobbles loses a little; a note that slides around loses a lot. Controlled vibrato is fine, wandering is not.

Because SongHub songs are MIDI-based, the reference melody is exact note data, not a guess extracted from audio. That makes the scoring unusually fair: the target it grades you against is the true melody, every time.

What the Numbers Mean

• 90 to 100: excellent. Performance-ready. Your pitch is locked and your timing is tight. Time to try a harder song.
• 80 to 89: solid. A good performance with a few drift spots, usually the bridge or the highest chorus notes. This is where most regular singers live.
• 70 to 79: developing. The song is slightly beyond your current comfort zone, or the key is wrong for your voice. Totally normal for new songs.
• Below 70: explore. Not a failure, a signal. The key probably does not fit, the tempo may be too fast, or the song needs a few practice runs.

Raising Your Score, the Honest Way

Start with the key. A huge share of low scores comes from fighting the original artist range. Drop the song into your comfortable zone with the key changer and watch the number jump, sometimes by ten points, with zero extra practice. The scoring grades you against the transposed melody, so there is no penalty.

Next, record your performances and compare takes. The section breakdown shows exactly where points leak: almost always the first line of each chorus and the bridge. Practice those eight bars in isolation, slow the tempo while learning, and re-record. Improvement you can measure is improvement that sticks.

Finally, pick the right material. Our beginner song list is full of songs with narrow ranges and forgiving melodies, the kind where high scores come naturally and build your confidence for harder tracks.

Scoring vs Real Singing Skill

An honest caveat: the score measures accuracy, not artistry. It cannot hear the emotion in a quiet verse, the character in a raspy tone, or the joy of a room singing along. Some of the most beloved karaoke performances of all time would score in the seventies. Use the number as a practice compass, not a verdict. When the room erupts, that is the only score that matters.
